Hello~ Can you help me say this naturally please?

Student: Sorry but it will be ok with you if I leave now?
Because I’m late for taking the last school-bus.


Teacher: Oh, ok. You can go now.


The student arrived at school-bus station.


Student: Excuse me?
ⓐHas school-bus passed already?
ⓑHas school-bus gone already?


A: Oh poor thing. It has just before passed (gone).

Those are both good. (Of course, in speech you don't need to worry about punctuation. However, you need a period instead of the first comma and a question mark instead of the second one.)
